A brief outline:

Lecture Definition of machining. Chipless forming as alternative to machining.

Cutting tools. Types and characteristics.

Tool materials. Coatings.

Kinematics of cutting process. Cutting conditions: cutting speed, feed rate and the depth of cut.

Machining process: formation and classification of chips, built-up edge of tool, heat and

temperature in cutting, cutting fluids.

Tool wear. Tool life curve.

Selection of cutting speed, feed rate and the depth of cut depending on production rate, costs,

tolerances and stage in cutting.

Cutting economics. Production rate vs cutting speed curve and machining costs vs cutting speed

curve. Machining costs vs tolerance curve.

Cutting machines: types and application.

Finish machining: grinding, honing, lapping, polishing. Advanced machining techniques:

electrochemical erosion, laser and water jet cutting.

Manufacturing of spur, bevel and worm gears.

Casting process. Moulding box, moulding material, flask, core and core box.

Casting materials.

Classification of casting processes.

Design requirements of casting (draft, the gating system, parting surface, shrinkage).

Basic of welding. Welding joint.

Different materials weldability depending on the type of welding process. Welding defects: main

causes, type of cracks, distortion.

Classification and industrial application of gas and arc welding.

Electric resistance welding, laser beam welding, plasma arc welding and electron beam welding.

Soldering, brazing and adhesive (gluing).

Design of welding joint.

Short theory of plasticity and metal forming. Typical stress vs strain diagram with various stages of

deformation. Flow curve. Temperature in metal forming: cold, warm and hot working.

Forging, rolling, sheet metalworking: bending, deep drawing and shearing (die cutting), press

forming.

Forming machines (rolling mill, forging machine, pres, drawing machine, swaging machine). Design

of forming manufacturing system (groups of machines or production line). Materials for forming

tools. Occupational safety and health.

Forming manufacturing process documentation. Examples of forming manufacturing processes.
